The Diagnostic Imaging Department at the Saint John Regional Hospital has received funding to build a 3-D Artificial Intelligence Lab. This lab has the potential to impact our New Brunswick patients through providing 3-D printed patient-specific anatomic representations of the patients’ pathology. The current study aims to investigate two complex reconstructive surgeries that have limited or no research conducted to-date in regards to the impact of 3D printing for pre-surgical planning. The first is for charcot neuropathic osteoarthropathy (Charcot foot), a serious lower-extremity complication found in patients with diabetes involving severe deformities that can ultimately lead to amputation of the affected limb. The second is for mapping of abdominal vasculature pre-operatively to harvest abdomen tissue with a blood supply for breast reconstruction after mastectomies for cancer. The objectives of the current study are: 1) To determine the practicability of using the of the new 3-D AI lab in point of care settings. 2) Determine the impact of using 3-D printing for surgical planning on intra-operative and patient outcomes. For objective 1 the measures of interest will be the requirements for requesting the print, timing from request to acquiring the print, cost and utility of the print received. For objective 2 we will conduct an ambispective cohort study in which the primary measures of interest operative time, blood loss, length of stay and intra-operative adverse events. Exploratory measures of interest are in regards to patient recovery and will include measures of disability, time to mobility, return to work and patient satisfaction.
